SEEPAGE JOINT.

Application led April 6, 1920. Serial No. 371,618.

To all whom it may concern Be it known that I, EDWARD W. N. BoosEY, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certa-in new and useful mprovement in Seepage Joints, and declare the following t'o be a full, clear, and exact description of the same, such as' will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawin s, which form a part of this specification. his invention relates to seepage joints for plumbing set in concrete, cement or other porous material, and an object of the invention is to provide a joint of a character to prevent moisture from flowing through-the porous material or along the surface of plumbing set therein and to discharge such moisture into the plumbing fixture. A. further object is to provide a joint forthe purpose stated that requires no machining or expensive operations of any character in the formation thereof subsequent to the cast- .ing of the arts. These objects and the several novel eatures of the invention are hereinafter more fully described and claimed,

.and the preferred form of construction of the invention is shown in the accompanying drawings in which- Fig. 1 is a cross section of a floor drain showing my improved joint,

Fig. 2 is a cross section of a pipe line showmg my joint as applied to abutting end selptions thereof embedded in concrete or the li e.

1n Fig. 1 is shown a floor sump or drain having an upper end or mouth 1 covered by the usual grating and set in the concrete. This portion 1 at the bottom is provided with an inwardly extending flange 5.` The lower portion 2 of the sump is provided with' a flange 4 and between the flanges 5 and 4 is provided an apertured lead plate or apron 7 which extends for a considerable distance about-the drain. The lower side of the llange 5 is corrugated as indicated at 6 which engages the upper surface of the plate 7 so that the corrugatons are open to the concrete or porous body above the plate 7. t Any water or fluid seeping into the concrete or between the concrete and the wall 3 of the member 1 on reaching the lead plates 7, may seep through the i corrugations 6` into the interior of the drain. By this arrangement the fluid thatv would ordinarily pass on through the concrete is stopped atthe lead plate and discharged through the discharge line of the fixture.

This same ty e ofjoint may be provided in various plum ingstructures where water may tend to seep through the concrete or between the concrete and the fixture. An instance of this is shown in Fig. 2 in which the pipe 4section 10 has an outwardly extending flange for boltinv to the end of an adjacent pi section. 'his end is corrugated asin icated at 11, which corrugations rest upon a lead plate 12 centrally apertured to permit How of fluid through the pipe line and any seepage through the concrete from the upper sur ace or seeping between the concrete and the pipe section finds its way to the llead the corrugations or channels 11 into t e pi line.

i y this arran ement water from the upper surface of t e Hoor is prevented from seeping through to a ceiling below and the concrete below' the plate at least is maintained in its normal dry state,

I have shown the corrugations 6 and 11 in the res ective views as bein fairly large. It is evi ent, however, that t ese need not be very deep as the amount of seepage is small and a surface that is rou hened sufiicient to .o rmt a flow of fluid tween the corrugat or roughened flange and lead pla-te will be all that is required. By making these corrugations comparatively' small, even less than one-sixteenth of an inch in depth, the concrete does not flow into the corrugations on placing of the concrete about the joint.

Having thus briefly described my invention, what l claim is- 1. In plumbing1 a seepage joint between attached parts of plumbing elements comprisin a flanged portion on the upper of said elements adapted to be attached to another element, an apron or plate rovided between the said elements and exten ing outwardly therefrom, the flange of the upper element being roughened or corru ated on the lower face substantially as an for the purpose. described.

2. A vseepage joint for use in plumbing-set in porous material com rising the combma tion with an upper an a lower element, of an apron or plate secured therebetween apertured to permit How of fluid through plate and then passes throu h crete, comprising like adapted to said elements, the upper element at the point of contact with the 4plate being provided with a passageway to the interior of the fixture for iiuld seeping through the porous material onto the plate.

3. A seepage joint for fioor sumps and the like adapted to be set in cement or conn the combination with the upper relvmg end of the sum and lower discharge endthereof adap to be attached together, of an apron or plate lying in the concrete between the two members centrally apertured to permit a, passage of fluid through the members, the .lower face of the upper member Contactin the apron being roughened or corrugate 'providing channels from the concrete abovethe plate to the interior of the sump.

4. A seepage gint for floor sumps and the set'in porous --cementitious material comprising the combination with the upper receiving end of the sump having an internal ange at the lower end, and the lower discharge end of the sump having an external flange of a diameter greater than the diameter of the lower end of the first part, of an apron or plate lying in the concrete between the two said ends and extending outwardly thereabout, the apron being.

centrally ajrturcd to permit passage of fluid throug the said members, the said internal flange of. the upper member being roughened or corrugated on the surface con tactlng the apron providing a. plurality of 1,4eap1e D ageways to the interior of the sump for uid flowing through the porous material onto'the plate.

5. A seepage joint for use in plumbing kSet in porous material comprising the combination with an u per and a lower element connected toget er each provided with a lateral ange material below t e upper surface, of an apron or plate secured between the said flanges and centrally apertured to permit flow of fluid through the connected elements, the flange of the upper element lying in contact with the upper surface of the apron having substantially radial grooves provided in the contacting face permitting a seepage of uid from the apron into the interior of the said plumbing elements.

6. A seepage joint for use in plumbing set in porous material comprisin the combination with an upper and a ower element united together, the said elements having lateral anges at the united ends below the upper surface of the porous material, of an apron secured between the said anges having an aperture registering with the openings in the ends of the elements, the upper element being formedI to provide openings into the interior thereof permitting seepag accumulating on the a ron to pass into t e interior of the plumb-lng element.

In testimony whereof I sign this specification.
